Aron Ralston Arm Cut Off?

Aron Ralston is the American mountain climber who made headlines in 2003 after he cut off his own arm in order to free himself from being trapped by a boulder for 127 hours.
I heard there are going to make a movie about Aron Ralston where they're going to show why he cut off his arm.
What is going to be the name of the movie and who is going to be the actor that makes Aron Ralston's role?

There is a new movie named 127 hours that tell the story of Aron Ralston's desperation and the moment he decides to perform the amputation. The actor is James Franco.

Aron Ralston used to be a mountaineer and a very brilliant man. He was a mathematical engineer in Intel and a student of mathematical engineering and French in Carnegie Mellon University. He left his job in Intel in 2002 so that he could fulfill his dream of climbing all of Colorado’s peaks that were above 14000 feet high.

Aron Ralston's biggest mistakes was not telling people where he was going on his solo trip to the canyon.

Ralston found himself trapped against a canyon wall—his right arm pinned under a dislodged boulder. About five days later (127 hours, to be precise), he proceeded to amputate his own arm. With a dull knife.
This movie is going to be good, can't wait to see it.
